EPM7256EGC192-15

Complex Programmable Logic Devices Overview

The Altera EPM7256EGC192-15 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000 family. It features 256 macrocells, 16 logic array blocks (LABs), and up to 164 user I/O pins within a 192-pin PGA package. The device operates at a supply voltage of 5 V with a maximum propagation delay of 12 ns and a maximum counter frequency of 90.9 MHz. It utilizes CMOS EEPROM technology for non-volatile configuration and supports reprogramming cycles.

Complex Programmable Logic Devices Feature Summary

• Contains 256 macrocells organized into 16 LABs with 5,000 usable gates.
• Features a 192-pin Ceramic Pin-Grid Array (PGA) package providing 164 I/O pins.
• Operates on a single 5.0 V power supply with a maximum propagation delay of 12 ns.
• Supports high-speed operation with a maximum counter frequency of 90.9 MHz.

Complex Programmable Logic Devices Applications

• Complex address decoding and bus interfacing in embedded systems.
• Replacement for legacy discrete logic families such as PALs, GALs, and pLSI devices.
• Implementation of state machines and timing control circuits requiring moderate I/O density.

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific ordering suffix matches the required package type and speed grade. Check for moisture sensitivity levels and storage conditions prior to installation to ensure device reliability.

Complex Programmable Logic Devices Selection Notes

Select this model when a 5 V supply is required and a PGA package is preferred for high pin count applications. Compare against MAX 7000S variants if In-System Programmability (ISP) via JTAG is necessary, as standard MAX 7000E devices may lack these specific interface features.

Complex Programmable Logic Devices Part Context

This component is part of the MAX 7000 family, which represents Altera's second-generation CPLD architecture. The family provides a range of logic densities from 600 to 5,000 gates. The EPM7256E variant specifically targets designs requiring higher I/O counts and larger logic capacity within the standard 5 V MAX 7000 ecosystem.

Complex Programmable Logic Devices Replacement Considerations

For functional equivalents with ISP capabilities, consider the EPM7256S series. For lower voltage operations, evaluate the MAX 7000A or MAX 7000B families, noting that pin compatibility exists but voltage requirements differ significantly.
